Height of the group member’s eye level : 1.7m
How far away from the flag pole they were standing :4m (add an additional 0.12 m because the base of the flagpole is thicker at the bottom.

Results & Conclusion
5. We had quite a few considerations to take while completing this lab. One of the things we had to modify a little bit was the distance in between the person standing and the flagpole because the base of the flagpole was a little bit thicker, so we had to add an extra 0.12m to the distance. Another consideration we had to take was the eye height from which we were measuring, since we needed to add that height to the total height of the flagpole.
6. With most groups that we compared our answer to, their answer was pretty close to ours, so we were quite sure we measured it right. There were a few groups that had a slightly different answer, but the difference was no more than 1m. I think that the reason there were differences was because the clinometers were really hard to read, and everyone had a different angle, since most people just approximated the angle. Other than that, I think we did a pretty good job at accurately measuring the height of the flag pole.
7. Trigonometry can be used to measure very high things, that they cannot measure with a meter stick, or even those things that are too hard to measure. I think that when we measure things that are very high, we can easily determine the distance we are standing from it by simply measuring with a meter stick. Measuring the angle will be harder, but it is possible, with devices like clinometers. So if we have the angle and the distance that we are standing from the object, we know enough information to calculate its height.
